Cette étude s'inscrit dans le cadre du programme d'essais scientifiques et technologiques de démonstration du projet Cigéo, le projet français de centre de stockage profond (500 m environ) de déchets radioactifs. Elle est en lien avec l'analyse du comportement de différents types de revêtements qui doivent satisfaire des exigences en termes de tenu...
This paper presents the use of a specific layer-wise approach to analyze the results of a FABAC accelerated loading test (ALT) carried out on a flexible pavement with an initial flaw. The approach relies on M4-5n (Multi-particular Model of Multilayer Materials) initially developed for the analysis of debonding in composite materials. M4-5n was rece...
In this paper we present the results of the national French project SolDuGri dealing with pavement reinforcement by glass fiber grids. In this project, an accelerated pavements test (APT) was performed on 6 pavement sections to evaluate the in situ performance of the reinforcement on their lifetime. The tests consisted in building test sections wit...
Monitoring pavement condition during its service life is paramount in order to antici-pate and optimize the potential maintenance work. For this purpose, different non-destructive techniques (NDT) are used to evaluate the structure distresses condition and to provide necessary information for the maintenance tasks. On their own, they are limited to...
Truck platooning for the transportation of loads is a strategy recently proposed by the automotive sector to cope with traffic congestion, fuel consumption, and operational costs. This new way of configuring trucks changes the typical pressures pavements structures experience. For this reason, the research efforts of the pavement sector should be a...
In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...
Investigation of the behavior of limetreated soil with emphasis on laboratory and field implementation technics and microstructural observations is made. Field investigation of a 7-year atmospherically cured embankment, thanks to measurement of sampled materials performances, shows a significant evolution in compressive strength, evidencing the lon...

This paper focuses on the physicochemical changes that happen in cold mix asphalts during curing, and more specifically, while and after transitioning to different simulated seasons. Several tests were carried out in order to better grasp the influence of the weather (temperature and humidity) on the curing of such materials. The mechanical behavio...
Dust emission is a major issue in general but even more for civil engineering professionals. This is particularly important on earthmoving sites with truck traffic on compacted soils. Suspended dust causes many troubles, including visibility mitigation, which leads to safety risks. To prevent the lift of particles, soils are watered abundantly. Whe...
An experimental campaign was carried out on a test track to assess resuspension of dust by vehicle traffic. Two vehicles were driven on a road covered by four different types of particles representing a wide range of fine soils. Each test consisted of running one of the vehicles at a given speed (30, 45 or 60 km.h-1) over one of the type of particl...
